In Reply to: What effect does slew rate have on audio reproduction. posted by grandpoof2 on May 18, 2001 at 13:47:24:
The slew rate of the output drivers generally determines the bandwidth of the amp, however, this is usually specified into a particular specified load, like 8 ohms pure resistive. Slew rate can be affected by adding complex inductive/capacitive loads. I'm not sure there is really any industry standards, like there are for frequency response, so the conditions of this measurement may vary significantly from amp to amp. In any case, higher slew-rate is always better, because it prevents amplitude roll-off and phase shift at the highest audio frequencies. Comparing amps using slew-rate may be problematic, because it may not be apples-to-apples.A fast slew-rate might be 100V/Usec and a slow one might be 1V/Usec.
